What it controls

The Honeywell Home HZ221 Zone Control Panel is a zone panel for 2 zone.

In a zoned system each area's thermostat opens its dampers through the panel, so one floor can be heated or cooled without the other. A contractor sizes it so a single small zone can run safely. Sensors or zoning?

Voltage, per the listing: 24 V.
